Download MSEide+MSEgui for free. MSEide is a Rapid Application Development IDE for platform independent rich GUI applications in the Pascal language. It comes with its own GUI toolkit called MSEgui, which ensures programs are portable.

MSEkicadBOM uses pcbnew.py as interface to pcbnew. In pcbnew.py there is a “BuildHolesList()” function with the signature “EXCELLON_WRITER self, LAYER_PAIR aLayerPair, bool aGenerateNPTH_list”.
How must the LAYER_PAIR type parameter be defined in Python?
Thanks, Martin
